Stepping up the security cover for Independence Day, officials said borders will be sealed and entry and exit at Metro stations near Red Fort will remain closed till Prime Minister Narendra Modi is at the venue. The capital remains on high alert in the wake of terror threats and attacks on several countries across the globe.

At least 30 companies of paramilitary force and Delhi Police personnel will be on duty during the celebration at Red Fort. While the inner circle will be guarded by paramilitary personnel, the outer ring will be guarded by Delhi Police. Buildings and prominent installations around Red Fort have been scanned, said a source.

A police officer said personnel will be deployed on routes leading to Red Fort. A few roads from the Prime Minister’s residence at 7, Race Course Road, will be monitored by CCTV cameras. As many as 500 CCTV cameras have been installed across New Delhi, central and north districts, said officials.

Snipers will be stationed, and panoramic photography will be used to keep a watch on 605 balconies and 104 windows that open towards Red Fort. Spotters will keep an eye on parking areas and sniffer dogs will be a part of the arrangement, said officials.
